Customer has complained her HIC3C33CWEUK integ dishwasher is sticking on drain during most programmes and showing 3 in the display. Not doing it on Eco was but nearly always on others. Presuming it’s drain timeout as per Hotpoints code page but what senses this, turb sensor?? Not stripped it down to check loom yet (Fri 7.30) so just getting a bit of info if poss chaps.:)
